#### 1

**Receives signal**  
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster  

#### 2

**Boosts signal**  
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.  

#### 3

**Broadcasts signal**  
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.  
  

  

#### **Get stronger signal**

#### Normal Cell Coverage

Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.

![how 4G LTE Mobile Signal Booster UK Networks EE Vodafone O2 Indoor Coverage Improve Signal work for home office](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/ProductPageboostedcoverage-2.webp?v=1650634397)

#### Signal Coverage with our booster

Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.

#### **Installation**

1.  Connect the indoor antenna to the MS port.
2.  Connect the outdoor antenna to the BS Port.
3.  Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
4.  Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
5.  Power on the booster and check the signal strength.
6.  Adjust the outdoor antenna until you get the best signal strength.

**IMPORTANT NOTE**:  
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

1.  What is a mobile signal booster? - A mobile signal booster is a device that helps improve your phone's signal strength. It works by catching weak signals from outside, amplifying them, and then sending the stronger signal indoors. This is especially helpful if you live in an area where your phone often drops calls or has slow internet.
2.  How does the 3G - 300m2 mobile signal booster work? - The 3G - 300m2 mobile signal booster captures signals from outside your home or building. It then strengthens this signal and sends it inside, covering an area of about 300 square meters. This means you can enjoy better phone calls and faster internet browsing.
3.  Which mobile networks does this booster support? - This booster supports A1, Three, T-Mobile, Orange, Bob, and several others that operate on the 3G network. It's designed to improve signal strength for these networks, making it suitable for homes, cafes, restaurants, and more.
4.  Can the booster create a signal if there isn't one? - No, the booster cannot create a signal if there is no outside signal available. It can only amplify the existing signal. If you are in an area with no mobile service, the booster won't work.
5.  What do I need to install the booster? - To install the mobile signal booster, you’ll need the kit that includes an external aerial, booster base unit, indoor antenna, cables, and a power adapter. It’s designed to be easy to install with just a few steps!
6.  How long does installation take? - Installation is usually quick and straightforward. If you follow the manual, it can typically be set up in under an hour! You can do a 'loose' installation first to test the best locations for the antennas.
7.  What if I need a longer cable for installation? - If the standard 10-meter cable isn't long enough for your needs, you can upgrade to longer cables when purchasing the booster. Options include 20, 30, 40, and 50 meters.
8.  What is an external aerial, and do I need to upgrade it? - An external aerial captures the outside signal and is a crucial part of the booster setup. If your phone shows 1 or 2 signal bars, upgrading to a higher gain aerial can improve performance.
9.  How many devices can use the booster at the same time? - The 3G - 300m2 mobile signal booster can support up to 30 devices at once. This means multiple people in your home or business can enjoy better signals simultaneously!
10.  What should I do if I have more questions about the booster? - If you have more questions, you can visit our FAQs page or contact our support team for assistance. We are here to help you enjoy better mobile signal strength!
